Hi,

Please let me know the best opensource tool to find which system is utilizing more internet bandwidth.In my office I have 50 systems and would like to know which system is using more bandwidth as it seriously effects my LAN and no one is able to work as its completely goes slow.

Thanks

If you planning to monitor more than 50+ systems then you should go for Cacti (the best open source network bandwidth monitoring) tool for Linux, it gives complete statistics usage about your Network per host basis. Here is the guide on how to install and configure Cacti under RHEL/CentOS and Fedora systems. If you are using Debian based system, then there will be slight changes in commands…
